SYSTEM OVERVIEW The WIR TX90 two channel infrared transmitter combines infrared modulator and emitter technology into a single mountable enclosure - reducing operating cost and eliminating precious rack space. The WIR TX90 features an easy to use configuration preset for Music, Voice, or Hearing Assistance Applications. It operates on dual 2.3/2.8 or 3.3/3.8 MHz selectable frequencies - ideal for high quality audio programs such as music, theater and audio description.
u DETERMINE COVERAGE AREA Determine the coverage area needed for the seating area. When using the WIR TX90 transmitter with the RX22-4 receiver, in single channel mode, the WIR TX90 can achieve a coverage area of 28,000 ft2 (2,600 m2). In four channel mode, the WIR TX90 divides its power among the four signals to achieve a coverage area of 11,000 ft2 (1,022 m2). NOTE: The coverage area will vary depending on the sensitivity of the infrared receiver being used.

POWER CONNECTION FOR U.S.
u CONNECT AUDIO SOURCE Determine the length of the audio cable needed to connect to the sound system to the WIR TX90 transmitter. Install the supplied Phoenix connector on the end of the audio cable to be connected to the transmitter. See the back of the WIR TX90 for wiring instructions. FIGURE 9: AUDIO SOURCE CONNECTIONS The WIR TX90 will accept line level, balanced or unbalanced audio inputs.
u SELECT AUDIO PROCESSING APPLICATION PRESET The WIR TX90 offers three preset audio processing options for the most common applications: Music, Voice, and Hearing Assist. Use the “Music” setting when maximum dynamic range and audio quality are preferred. Use the “Voice” setting for simultaneous interpretation, audio description, or other applications with users that have primarily normal hearing.
USING THE OPTIONAL WIR TX9 SLAVE EMITTER FOR ADDITIONAL COVERAGE For larger facilities, additional emitter panels can be used to increase the overall coverage area. In these cases, we recommend using the WIR TX9 slave emitter in tandem with the WIR TX90. The WIR TX90 can drive multiple WIR TX9 emitters at one time. Each TX9 emitter will require its own power supply.
RECEIVER SAFETY INFORMATION HEARING SAFETY Williams Sound receivers are designed to amplify sounds to a high volume level which could potentially cause hearing damage if used improperly. To protect your hearing and the hearing of others: CAUTION! 1. 2. 3. 4. BATTERY SAFETY Make sure the volume is turned down before putting on the earphone or headphone before adjusting the volume to a comfortable level. Set the volume level at the minimum setting that you need to hear.
